Abstract
The present application relates to curtain wall construction technical field, especially to a kind of inclined curtain wall exquisite steel keel prestress exerting method, application to prestressed tensioning device in implementation process, the device includes three-dimensional tooling platform, positioning mechanism and tensioning mechanism;Method steps include: cutting, straightening and beveling to narrow plate and wide plate;Positioning mechanism and tensioning mechanism are installed on three-dimensional tooling platform;The end portion of narrow plate away from tensioning mechanism and the end portion of wide plate away from tensioning mechanism are temporarily welded and fixed;Steel keel is placed in positioning mechanism, and the end portion of narrow plate is connected with tensioning mechanism;Narrow plate is applied to stress in stages;After prestress exerting reaches design value, keep tension stable, after segment welding, steel keel is removed and continues to complete full welding process.The present application inserts prestress exerting process before steel keel is welded and formed, strengthens the physical properties of steel keel under complex stress state, avoids that keel is deformed due to span mid-span bending moment, and guarantees use safety and sealing effect.
